Application mm January 22, 1912. Serial No. 07am.

To all whom-it may concern:

Be it known that I, JOHN D. HOUOK, a citizen of the United States,residingat Chicago, in the county of Cook and State of Illinois, haveinvented certaln new and useful Improvements in Key-Holding Chains; andI do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the'same, reference being hadto the accompanying drawings, and to the letters and figures ofreference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in key holdingchains and the ob ect in view is to roduce a simple and eficient deviceof this nature, embodying various details of construction, combinationsand arrangements of parts which will be hereinafter fully described,shown in the accompanying drawings and then specifically defined 1n theappended claims.

- I illustrate my invention in the accompanying drawings, in which IFigure 1 is a perspective view of my key holding chain showin the partsassembled. Fig. 2 is a central ongitudinal sectional view, and Fig. 3 isa detail view of an identification sleeve mounted within one of thebarrel sections.

Reference now being had to the details of the drawings by letter, Adesignates a link chain, and B and C designate two hollow cylindricalbarrel sections, each apertured at its outer end. An eye D is swiveledin the aperture at the end ofv the section B- to which one end of thechain is fastened, and E is a screw which telescopes within the sectionC and has a hook F mounted therein with a shank portion fastened theretoand which shank portion extends through the aperture or slot F in whichthe hook is adapted to be normally seated when the two barrel sectionsare held together. The section B has integral threads adapted to receivesaid screw, forming means whereby the two arts may be screwed together,the hook catc ing in the slot at the end serving to anchor the screwwhile the barrel section B is screwed tightly against the section C.Said hook is adapted to engage the other end of the chain when thepartsare assembled and. be held to the hook in the manner shown anddescribed. A spring T is mounted upon the shank portion of the hook andinterposed between The screw with the wire,

designatedby letter N, which is open and .c lindrical ended and adaptedto fit within t e barrel portion B and. in which the name or the ownerof the chain may be rolled up and inserted therein. If desired, wording,as shown in the drawings, may appear upon the outer circumference ofeach of the barrel sections, designating that within may be found anidentification card.

In assembling the parts, one end of the chain is connected to theswiveled eye D. which is afterward bent to form a hook, has the coiledspring placed over said wire, after which the wire and screw areinserted in the barrel section 0, the wire passing through the slot F,after which a hook F is formed in the wire, thus preventing the screwbeing withdrawn from the barre section C. The coiled spring normallyunder tension will tend to hold the end of the hook in the slot F. Inorder to connect the chain with the hook F, the latter may bewithdrawnunder tension of the spring from the slot a sufiicient distanceto allow the link to be caught over the hook,

after which the spring will draw the hook back and retain the end of thechain. The identification member N is inserted in the barrel portion B,after which the two barrel sections may be screwed together in themanner shown in Fig. 2 of the drawings.

What I claim to be new is I 1. Akey chain comprising two separablebarrel sections, an eye swiveled to one of said sections, a chainfastened to said eye, a screw mounted in the other section and adaptedto engage integral threads upon the section to which the eye isswiveled, a hook fastened to said screw and passing through a slot inthe other section and adapted to be attached to one end of the chain,and a spring interposed between the inner end of the screw and theadjacent inner end of the section through which said hook passes, as setforth.

2. A key chain comprising two separable barrel sections, one having aperforation in the end in which an eye is swiveled, the

other provided with a slot in its end, achain' fasteped to eye, a screwhaving interior froln rotating independent of the slotted threadedconnection w1th the section to barrel section when the two sections aredewhich the eye is swlveled, a hopkl having a tached from each other, asset forth.
